かつた。However, in the past, in order to investigate the carbonization process of coal, only the method of extracting the physical change in the carbonization process and individually measuring only that change was adopted. For example, as shown in "3rd Edition Iron and Steel Handbook, Volume II, Iron and Steelmaking", pages 199 to 200, the dissolution that occurs in the carbonization process of coal depends on the solubility of coal when heated using a Giesela plastometer. taking measurement. For expansion and contraction during dry distillation, an expansion / contraction curve is obtained with a dilatometer. However, heretofore, there has been no suitable means capable of continuously observing the carbonization process of coal continuously from normal temperature to the carbonization temperature.
